About this task
The server supports one 3.5-inch SAS/SATA 12-bay backplane.
Attention: 
•  Read 
“Installation Guidelines” on page 35 and “Safety inspection checklist” on page 36 to ensure that you 
work safely.
•  To avoid damage to the drive connectors, make sure that the server top cover is in place and fully closed 
whenever you install or remove a drive.
•  To make sure that there is adequate system cooling, do not operate the server for more than two minutes 
without either a drive or a drive bay filler installed in each bay.
•  Before you make changes to drives, drive controllers (including controllers that are integrated on the 
system board assembly), drive backplanes, or drive cables, back up all important data that is stored on 
drives.
